The DTC123JE3HZGTL is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors within a compact SOT-416 (EMT3) surface-mount package. This component integrates R1 and R2 to simplify circuit design by eliminating external input resistors. Key electrical specifications include a maximum collector current of 100 mA, a collector-emitter voltage rating of 50 V, and a transition frequency of 250 MHz. The device supports a power dissipation of 150 mW and operates within a temperature range of -55°C to +150°C. It meets AEC-Q101 automotive grade standards, ensuring reliability for demanding applications.
Verify the specific suffix HZGTL against the official datasheet to confirm the exact packaging format and tape-and-reel specifications. Ensure the source document explicitly lists this part number as recommended for new designs, as some variants in the DTC123 family may carry different status classifications or obsolete warnings.
Select this component when an NPN digital transistor with a 50V rating and 100mA continuous current capability is required. The built-in resistor ratio simplifies base drive calculations. Confirm that the SOT-416 footprint matches the PCB layout constraints and that the thermal performance of the 150mW dissipation rating is sufficient for the intended operating environment.
This part belongs to the ROHM DTC123 series of bias-resistor-built-in transistors. The JE3 suffix typically denotes specific automotive-grade reliability and packaging variations compared to standard commercial versions. It serves as a direct replacement for discrete resistor-transistor networks in switching applications.
DTC123JE3TL is a verified substitute within the same series offering identical pinout and electrical characteristics in the SOT-416 package.
